Titration Lab of NaOH and KHP Aim: To titrate Sodium Hydroxide with Potassium Hydrogen Phthalate . To also determine the concentration of NaOH in the KHP solution. Hypothesis: When KHP is added to the solution of NaOH and the indicator‚ the solution will turn clear and neutralize. The concentration of NaOH is going to be very low because it is diluted. Materials required: pipette filler‚ volumetric flasks(2-4)‚ beakers(2)‚small white piece of paper‚ indicator( 2 drops)‚ conical flask‚ clamp

SCIENCE TITRATION SIMULATION ! TRIAL 1:! This reaction was strong acid vs. strong base! ! Known: Acid! Unknown: Base HCl NaOH Volume! 25.00 mL 18.66 mL Molarity 0.1396 M Uknown Name! Indicator ! Methyl Orange! Turned red when mixed with the acid solution.! After adding 18.66 mL of base‚ turned orange. After having added the correct amount of base to the acid solution mixed with indicator‚ we can calculate the concentration of the base solution

Redox Titration Lab ABSTRACT: In this lab‚ 0.010 M purple-colored potassium permanganate solution was standardized by redox titration with iron (II) ammonium sulfate hexahydrate (FAS). The average mass of the three flasks of FAS was 0.483 grams. Once the concentration of the standard solution of KMnO4 (aq) was determined‚ it was used to determine the concentration of Fe2+ in iron pills. On average‚ there was 0.01813 L of solution used. With this information and the balanced net-ionic equation

Potentiometric Titrations Accuracy The accuracy of a potentiometric analysis is limited by the measurement error for the cell’s potential. Several factors contribute to this measurement error‚ including the contribution to the potential from interfering ions‚ the finite current drawn through the cell while measuring the potential‚ differences in the analyte’s activity coefficient in the sample and standard solutions‚ and liquid junction potentials. Errors in accuracy due to interfering ions

1. At a study session before a midterm exam you heard four of your friends chatting: Explain each statement‚ using utility analysis. a.“I think Joshua paid too much for his backpack.” --The speaker does not receive as many utils from shopping for backpacks as Joshua. b.“I gave Eddie $20. He really needed it more than I do.” --Money is not as important to this person‚ Eddie will get more utils out of each dollar then the person who gave him the money. c.“I didn’t go to the concert last night because

The Disadvantages of Using SWOT Analysis by Steven Symes‚ Demand Media SWOT analysis‚ strength‚ weakness‚ opportunities and threats analysis‚ provides a structure for organizations‚ including small businesses‚ to analyze it internally. The analysis examines an organization’s assets‚ processes and past levels of achievement. While SWOT analysis provides some benefits to an organization‚ using it in your small business can put you at a disadvantage unless you understand its limits and risks. Other

Sometimes known as the STEP analysis‚ PESTEL stands for Political‚ Economic‚ Social‚ Technical‚ Environment and Legislative. It is a great tool for any size organization who would like to have a simple to use tool for understanding the external forces influencing their market and performance. If you would like a good tool for external forces‚ I would recommend using this one. PESTEL is a strategic planning tool; it helps you see the landscape beyond your own market. This is important because

Background Knowledge of the dissolved oxygen (O2) concentration in seawater is often necessary in environmental and marine science. It may be used by physical oceanographers to study water masses in the ocean. It provides the marine biologist with a means of measuring primary production - particularly in laboratory cultures. For the marine chemist‚ it provides a measure of
